A one-dimensional optomechanical crystal with a complete phononic band gap

J. Gomis-Bresco, D. Navarro-Urrios, M. Oudich, Said El-Jallal, A. Griol, D. Puerto, E. Chavez, Yan Pennec, Bahram Djafari-Rouhani, F. Alzina, A. Martínez, C.M. Sotomayor Torres

Recent years have witnessed the boom of cavity optomechanics, which exploits the confinement and coupling of optical and mechanical waves at the nanoscale. Among their physical implementations, optomechanical (OM) crystals built on semiconductor slabs enable the integration and manipulation of...

Transmission and attenuation of Lamb waves through a periodic array of rectangular slits in a plate

Rayisa P. Moiseyenko, Yan Pennec, Rémi Marchal, Bernard Bonello, Bahram Djafari-Rouhani

Acoustic wave transmission through sub-wavelength slits or holes, then on layers of periodically spaced cylinders and double fishnet structures, known as acoustic metamaterials has been studied in many works in relation with physical phenomena such as extraordinary resonant transmission, sound...

Theory and simulation of optomechanical effects in phoxonic crystals

Said El-Jallal, Mourad Oudich, Yan Pennec, Abdelkader Makhoute, Jordi Gomis-Bresco, Daniel Navarro-Urrios, Clivia M. Sotomayor Torres, Alejandro Martínez, Bahram Djafari-Rouhani

Phoxonic crystals are periodic structures that can exhibit dual phononic and photonic band gaps, thus allowing the simultaneous confinement of both acoustic and optical waves inside the same defect such as a cavity or a waveguide. Then, one can expect an enhancement of the phonon-photon interaction...

Broadband sound shielding of Lamb waves through a periodic array of junctions

R.P. Moiseyenko, Yan Pennec, R. Marchal, B. Bonello, Bahram Djafari-Rouhani

We study theoretically sub-wavelength physical phenomena such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. One of the main results is the demonstration of a...

Insulin loaded iron magnetic nanoparticle–graphene oxide composites: synthesis, characterization and application for in vivo delivery of insulin

Kostiantyn Turcheniuk, Manakamana Khanal, Anastasiia Motorina, Palaniappan Subramanian, Alexandre Barras, Vladimir Zaitsev, Victor Kuncser, Aurel Leca, Alain Martoriati, Katia Cailliau-Maggio, Jean-Francois Bodart, Rabah Boukherroub, Sabine Szunerits

One of the focal subjects in insulin delivery is the development of insulin formulations that protect the native insulin from degradation under acidic pH in the stomach. In this work we show, for the first time, that a graphene oxide (GO) based matrix can ensure the stability of insulin at low pH....

Band gap formation and elastic wave transmission in two-dimentional surface phononic crystal

Sergey Yankin, Abdelkrim Talbi, Yu Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

Using finite element method analysis of surface acoustic wave (SAW) propagation in the phononic crystal in a form of periodic lattice from nickel pillars, located on a piezoelectric substrate of Y+128°-cut LiNbO3, has been conducted. Amplitude and phase characteristics of SAW propagation through...
